Question

A binomial has been partially factored, as shown below: x2 − 25 = (x + 5)(_____) Which of the following binomials represents the missing factor? (x − 5) (x + 5) (x − 20) (x + 20)

Answer 1

I got x-5, and it was correct. Hope this helps you, have a great day! :)

Answer 2

The equation has -25, so the factored answer needs to be able to multiply and have a negative answer.

The missing part would be (x-5)

5 x -5 = -25
